A startup has started selling a battery that helps solar and wind power operate in remote locations.
The batteries cost about as much as lead-acid ones, which are sometimes used now, but they last twice as long, effectively cutting the long-term costs in half (see “Demo: Storing the Sun”). Other long-lived batteries exist, but they cost far more than lead-acid batteries.
The new energy storage technology could be crucial to making renewable energy more viable, especially in remote locations. By making solar power cheaper than diesel fuel in many places, it could help bring clean power to some of the more than one billion people in the world without reliable electricity (see “A Billion People in the Dark”).
As costs come down further, the batteries could find new applications beyond microgrids, including stabilizing conventional power grids as they come to rely more heavily on renewable energy.
The company isn’t disclosing where its batteries are being used—except to say the projects are international
